A dental tray system comprising:

• a dental tray having a body having at least one channel for receiving a quantity of photocurable dental material and a light conductor, and
• a light engine having at least one battery or is connectable to an electrical power source and at least one light source,
• wherein the light source is capable of connecting to the dental tray such that the light source is optically coupled to the light conductor,
• wherein said light conductor extends along said body of the dental tray and is oriented toward the internal and external portion of a dental arch to allow for adequate curing of the dental material in the body and the dental material that overflows outside the body,
• wherein the light conductor is a light pipe,
• wherein the body has an upper portion and a lower portion, and the light pipe is sandwiched between the upper portion and lower portion, and
• wherein the upper portion and lower portion are integrally connected to each other such that the upper portion and lower portion will not separate, and
• wherein the upper portion includes mechanical retaining features at a bottom of the upper portion that in combination with walls of the dental tray are capable of retaining a majority of the photocurable dental material within the dental tray.
